DETAILED DESCRIPTION

Initial Considerations

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

The present application uses formal outline headings for clarity of presentation. However, it is to be understood that the outline headings are for presentation purposes, and that different types of subject matter may be discussed throughout the application (e.g., devices/structures may be described under processes/operations headings and/or processes/operations may be discussed under structures/processes headings; and/or descriptions of single topics may span two or more topic headings). Hence, the use of the formal outline headings is not intended to be in any way limiting.

Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

In some implementations described herein, logic and similar implementations may include software or other control structures. Electronic circuitry, for example, may have one or more paths of electrical current constructed and arranged to implement various functions as described herein. In some implementations, one or more media may be configured to bear a device-detectable implementation when such media hold or transmit device-detectable instructions operable to perform as described herein. In some variants, for example, implementations may include an update or modification of existing software or firmware, or of gate arrays or programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation may include special-purpose hardware, software, firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components. Specifications or other implementations may be transmitted by one or more instances of tangible transmission media as described herein, optionally by packet transmission or otherwise by passing through distributed media at various times.

Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of virtually any functional operations described herein. In some variants, operational or other logical descriptions herein may be expressed as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, implementations may be provided, in whole or in part, by source code, such as C++, or other code sequences. In other implementations, source or other code implementation, using commercially available and/or techniques in the art, may be compiled//implemented/translated/converted into a high-level descriptor language (e.g., initially implementing described technologies in C or C++ programming language and thereafter converting the programming language implementation into a logic-synthesizable language implementation, a hardware description language implementation, a hardware design simulation implementation, and/or other such similar mode(s) of expression). For example, some or all of a logical expression (e.g., computer programming language implementation) may be manifested as a Verilog-type hardware description (e.g., via Hardware Description Language (HDL) and/or Very High Speed Integrated Circuit Hardware Descriptor Language (VHDL)) or other circuitry model which may then be used to create a physical implementation having hardware (e.g., an Application Specific Integrated Circuit). Those skilled in the art will recognize how to obtain, configure, and optimize suitable transmission or computational elements, material supplies, actuators, or other structures in light of these teachings.

Removing Carbon Dioxide from Combustion Gas from an Engine of a Vehicle

Following are a series of flowcharts depicting implementations. For ease of understanding, the flowcharts are organized such that the initial flowcharts present implementations via an example implementation and thereafter the following flowcharts present alternate implementations and/or expansions of the initial flowchart(s) as either sub-component operations or additional component operations building on one or more earlier-presented flowcharts. Those having skill in the art will appreciate that the style of presentation utilized herein (e.g., beginning with a presentation of a flowchart(s) presenting an example implementation and thereafter providing additions to and/or further details in subsequent flowcharts) generally allows for a rapid and easy understanding of the various process implementations. In addition, those skilled in the art will further appreciate that the style of presentation used herein also lends itself well to modular and/or object-oriented program design paradigms.

Referring to FIGS. 1A and 3 and given by way of overview, an illustrative method 100 (FIG. 1A) is provided for removing carbon dioxide from combustion gas 10 (FIG. 3) from an engine 12 (FIG. 3) of a vehicle 14 (FIG. 3). The method 100 starts at a block 102. At a block 104, carbon dioxide is removed from the combustion gas 10 in a first vessel. At a block 106, material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 is stored in a second vessel. At a block 108, the material that contains carbon associated with the carbon dioxide removed from the combustion gas is removed from the vehicle 14. The method 100 stops at a block 110.

The method 100 will be explained first. An illustrative system 200, including its components, will be explained next and the vehicle 14 then will be explained. Illustrative details will be set forth below by way of non-limiting examples.

It will be appreciated that the vehicle 14 may include any type of vehicle whatsoever that includes an engine 12 which produces carbon dioxide emissions that are present in the combustion gas 10 that is exhausted from the engine 12. Accordingly, no limitation to the type of vehicle 14 is intended and is not to be inferred. Thus, the vehicle 14 may include, by way of illustration only and not of limitation: a land conveyance such as an automobile, a car, a truck, a van, a train, a farm implement such as a tractor or the like, a military vehicle such as a tank or a personnel carrier or the like; a water-borne conveyance, such as a surface ship like a maritime vessel or a pleasure craft or a naval vessel, or a submarine (with a diesel engine); or an aerial conveyance such as a fixed-wing aircraft or a rotary wing aircraft.

The engine 12 may be any type of internal combustion engine as desired for a particular application. For example, the engine 12 may be an internal combustion engine that uses a hydrocarbon fuel, such as gasoline or diesel fuel. In some embodiments, the engine 12 may be disposed in an internal combustion engine in a hybrid vehicle in which fuel may be switched between a hydrocarbon fuel for the engine 12 and electricity to power an electric motor. In some applications, fuel for the engine 12 may be determined by the vehicle 14 in which the engine 12 is disposed. For example, in embodiments in which the vehicle 14 is embodied as a submarine, the engine 12 is a diesel engine.

Referring additionally to FIG. 1AK, in some embodiments storing in a second vessel material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 at the block 106 may include storing in a removably replaceable second vessel material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 at a block 182.

In a related aspect and referring additionally to FIG. 1B, in some embodiments removing from the vehicle 14 the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 at the block 108 may include removing from the vehicle 14 the second vessel.

Given by way of non-limiting example for illustration purposes only, the second vessel (that contains carbon associated with the carbon dioxide removed from the combustion gas 10) may be removed from the vehicle 14 and brought to a collection or exchange facility that accepts containers (such as the second vessel) that contain carbon associated with the carbon dioxide removed from the combustion gas 10. However, it will be appreciated that, in other applications, the second vessel need not be brought to such a collection or exchange facility.

In some other embodiments and referring additionally to FIG. 1C, if desired an empty second vessel may be reinstalled on the vehicle 14 at a block 114. In such cases, it will be appreciated that an empty second vessel may be obtained from a collection or exchange facility as described above. Thus, given by way of non-limiting example, in such a case the second vessel (that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be removed from the vehicle 14 at the block 112 and brought to the collection or exchange facility and exchanged for an empty second vessel, which is reinstalled on the vehicle 14 at the block 114. However, it will be appreciated that an empty second vessel need not be obtained from such a collection or exchange facility and may be obtained from any source as desired.

It will be appreciated that the carbon dioxide may be removed from the combustion gas 10 in any manner desired. For example and referring additionally to FIGS. 1A, 1D, and 3, removing in a first vessel carbon dioxide from the combustion gas 10 at the block 104 may include absorbing the carbon dioxide in a liquid solution. Given by way of example only and not of limitation, the liquid solution may include without limitation a chemical solvent absorber, like an alkanolamine solvent such as without limitation monoethanolamine (MEA), methyldiethanolamine (MDEA), diethanolamine (DEA), piperazine, diisopropanolamine (DIPA), diglycolamine (DGA), and/or triethanolamine (TEA). In some embodiments, carbonic anhydrase may be used with the chemical solvent absorber to increase carbon dioxide absorption rates.

Given by way of further examples, in some embodiments the liquid solution may include amine-modified room temperature ionic liquids (“RTILs”), such as without limitation amine-solubilized RTILs (“RTIL-amines”) and/or amino functionalized RTILs (task-specific ionic liquids, or “TSILs”).

In some other embodiments and given by way of further examples, the liquid solution may include aminoacid metal salts with piperazine. For example, the aminoacid metal salt may include without limitation potassium dimethylaminoacetate. In some other embodiments, the liquid solution may include amino-amides, such as without limitation diethylaminoacetamide.

In some embodiments and referring additionally to FIG. 1E, absorbing the carbon dioxide in a liquid solution at the block 116 may include passing the combustion gas through a liquid solution at a block 118. In some other embodiments and referring additionally to FIG. 1F, absorbing the carbon dioxide in a liquid solution at the block 116 may include passing the combustion gas over a surface of a liquid solution at a block 120.

It will be appreciated that, in some embodiments, the first vessel has a first pressure and the second vessel has a second pressure that is less than the first pressure. In such cases, a pressure differential can help prevent backflow from the second vessel to the first vessel. Also, in some embodiments (and depending upon the removal modality), a higher pressure may be entailed for removing carbon dioxide than is entailed for storing carbon dioxide.

In some embodiments and referring to FIGS. 1A, 1D, 1G, and 3, if desired the removed carbon dioxide may be separated from the liquid solution at a block 122. Given by way of non-limiting example for purposes of illustration, the liquid solution may be heated in any manner as desired to a temperature sufficient to separate the carbon dioxide from the liquid solution, and the carbon dioxide is transferred to the second vessel for storage. Referring additionally to FIG. 1H, in some embodiments after the carbon dioxide is separated from the liquid solution at the block 122, if desired, the liquid solution may be recovered at a block 124. For example, the liquid solution from which the carbon dioxide has been separated may be cooled in the first vessel from its previously-elevated temperature, whereupon the liquid solution may once again be used for absorbing carbon dioxide.

In some other embodiments and referring now to FIGS. 1A, 11, and 3, removing in a first vessel carbon dioxide from the combustion gas 10 at the block 104 may include adsorbing the carbon dioxide with an adsorption material at a block 126. Given by way of example only and not of limitation, in some embodiments the adsorption material may include without limitation activated carbon, a metal-oxide-framework (MOF), silica gel, zeolite, a zeolitic-imidezolate-framework (ZIF), porous material, and/or mesoporous material. In some other embodiments and given by way of further examples, the adsorption material may include: RTILs such as imidazolium-based ionic liquids; and/or polymerized room temperature ionic liquids (“poly(RTILs)”).

Referring now to FIGS. 1A, 1J, and 3, in some embodiments, if desired, at least one attribute regarding removal of carbon dioxide from the combustion gas 10 may be determined at a block 128. The determination of the attribute at the block 128 may be performed at any point in the method 100 as desired for a particular application. Given by way of non-limiting examples, timing of determination of the attribute may depend in part on whether the attribute relates to outcome of a processing block that has already been performed, whether the attribute is relied upon by any further processing block, or the like. For example and referring additionally to FIG. 1K, in some embodiments and if desired after the attribute is determined at the block 128, data indicative of the at least one attribute may be communicated at a block 130.

It will be appreciated that the attribute may include any one or more attributes regarding any one or more aspects whatsoever regarding removal of carbon dioxide from the combustion gas 10 as desired for a particular application. Given by way of non-limiting examples, the at least one attribute regarding removal of carbon dioxide from the combustion gas 10 may include without limitation any one or more of the following attributes: position of the vehicle 14 where the carbon dioxide is removed from the combustion gas 10; time when the carbon dioxide is removed from the combustion gas 10; governmental regulations regarding removing carbon dioxide from combustion gas from an engine of a vehicle; an amount of pollution in air that is drawn into the engine 12; or the like.

It will be appreciated that the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may include various carbon-containing compounds, depending upon whether or not any additional processing is performed on the carbon dioxide removed from the combustion gas 10. For example, in some embodiments when no further processing is performed on the carbon dioxide removed from the combustion gas 10, the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may include carbon dioxide itself removed from the combustion gas 10.

In some embodiments and referring additionally to FIG. 1L, if desired at a block 132 the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be processed. As used in this application, “processing” means “reacting with a chemical reactant.” Accordingly, in some embodiments, processing the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 at the block 132 may include reacting the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 with a chemical reactant. For example and without limitation, in some embodiments and referring additionally to FIG. 1M, processing the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 at the block 132 may include transforming the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 into a hydrocarbon, such as without limitation a hydrocarbon fuel, at a block 134. Given by way of non-limiting examples, carbon dioxide may be reacted with natural gas to produce syngas (carbon monoxide and hydrogen) via “dry reforming”. Given by way of further non-limiting examples, carbon dioxide may be transformed to a hydrocarbon via chemical methods and via biochemical methods.

Regarding chemical methods, chemical transformations of carbon dioxide start with CO₂ (not CO₃ ²⁻, such as soluble carbonate salts like NaHCO₃ and Na₂CO₃), so (if carbon dioxide has been adsorbed) adsorbed carbon dioxide is first released from the adsorbent (such as by heating or under reduced pressure). Illustrative chemical methods may include, without limitation, transformation of carbon dioxide to methanol. In various embodiments, transformation of carbon dioxide to methanol may be accomplished via illustrative chemical methods such as without limitation catalytic hydrogenation (such as under high temperature and high pressure or via reduction of CO₂ with a silane using a stable N-heterocyclic carbene organocatalyst to produce a methylsilyl ether which is subsequently hydrolyzed to yield methanol). In another illustrative chemical method, electrochemical reduction of CO₂ in aqueous media generates CO and H₂ at the cathode in a ratio of approximately 1:2 while producing O₂ at the anode, and the generated CO and H₂ at the cathode are subsequently reacted to form methanol. In another illustrative chemical method, in a photoelectrochemical reaction reduction of CO₂ occurs at a p-type semiconductor electrode with a homogenous pyridinium ion catalyst using light energy.

Further illustrative chemical methods may include, without limitation, transformation of carbon dioxide to methane. In various embodiments, transformation of carbon dioxide to methane may be accomplished via illustrative chemical methods such as without limitation catalytic hydrogenation. For example, in an embodiment hydrogenation of CO₂ over a Fischer-Tropsch Co—Pt/Al₂O₃ catalyst yields methane as the major product together with small fractions of C₂-C₄ hydrocarbons. In some illustrative embodiments, in a solar photocatalytic reaction that uses arrays of nitrogen-doped titania nanotubes sputter-coated with an ultrathin layer of a platinum and/or copper co-catalyst(s), exposure of CO₂ and water vapor to sunlight produces methane as the major product. In other embodiments, an illustrative thermochemical reaction of CO₂ and H₂O yields methane by using reduced samarium-doped ceria that has been treated with a base-metal catalyst (such as Ni).

Further illustrative chemical methods may include, without limitation, transformation of carbon dioxide to a Fischer-Tropsch product. Given by way of non-limiting example, electroreduction of CO₂ over an un-electropolished Cu-electrode can produce hydrocarbons with a distribution similar to that obtained from the Fischer-Tropsch reaction of syngas.

Illustrative biochemical methods may include, without limitation, transformation of carbon dioxide to isobutyraldehyde and isobutanol. In some embodiments, genetically engineered cyanobacteria can convert either CO₂ or NaHCO₃ to isobutyraldehyde, and isobutyraldehyde is readily transformed to isobutanol. In some other embodiments, genetically engineered photosynthetic microorganisms can produce isoprene from CO₂ or CO₃ ²⁻.

As a further example and without limitation, in some other embodiments and referring additionally to FIG. 1N, processing the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may include transforming the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 into at least one compound chosen from a carbonate and a bicarbonate at a block 136. Given by way of non-limiting examples, the carbon dioxide may be reacted with a hydroxide, such as an alkali hydroxide. For example, the carbon dioxide may be reacted with sodium hydroxide to form sodium carbonate or sodium bicarbonate or with potassium hydroxide to form potassium carbonate or potassium bicarbonate, as desired.

As a further example and without limitation, in some other embodiments processing the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may include hydrating the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 to form carbonic acid. In embodiments in which carbonic acid is formed, the carbonic acid may be reacted with a carbonate, if desired.

In short, it will be appreciated that the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be reacted with any chemical reactant as desired.

It will also be appreciated that the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be stored while being processed. However, the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 need not be stored in order to be processed. Accordingly, in some embodiments, the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be processed without being stored.

In various embodiments the method 100 may include any one or more additional process blocks related to the material that contains carbon associated with carbon dioxide removed from the combustion gas 10 and/or removal of carbon dioxide from the combustion gas 10. Several examples will be given below by way of illustration and not of limitation.

For example and referring to FIGS. 1A, 1O, and 3, in some embodiments an amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be measured at a block 138. The measurement performed at the block 138 may measure volume and/or weight, as desired for a particular application. It will be appreciated that any measurement technique and sensors may be used as desired. In some other embodiments and referring additionally to FIG. 1P, the amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be displayed at a block 140.

In some embodiments and referring to FIGS. 1A, 1O, 1Q, and 3, an amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be determined at a block 142. For example, the amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was measured at the block 138) may be subtracted from the total amount of storage capacity available in an empty second vessel. In some embodiments and referring additionally to FIG. 1R, the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be displayed at a block 144.

In some embodiments and referring to FIGS. 1A, 1O, 1Q, 15, and 3, a rate of storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be determined at a block 146. For example, the amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was measured at the block 138) may be divided by time that elapsed during storage of the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10.

Referring additionally to FIG. 1T, in some embodiments an amount of time remaining to fill the storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be determined at a block 148. For example, the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was determined at the block 142) may be divided by the rate of storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was determined at the block 146). Referring additionally to FIG. 1U, in some embodiments the amount of time remaining to fill the storage capacity available for storing carbon material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was determined at the block 148) may be displayed at a block 150.

Referring additionally to FIG. 1V, in some embodiments a distance travelable in the vehicle 14 with the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was determined at the block 142) may be determined at a block 152. For example, the amount of time remaining to fill the storage capacity available for storing carbon material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was determined at the block 148) may be multiplied by speed of the vehicle 14. Referring additionally to FIG. 1W, in some embodiments the distance travelable in the vehicle 14 with the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 (that was determined at the block 152) may be displayed at a block 154.

Referring now to FIGS. 1A, 1X, and 3, in some embodiments time when carbon dioxide is removed from the combustion gas 10 may be recorded at a block 156. Referring now to FIGS. 1A, 1Y, and 3, in some embodiments position of the vehicle 14 where carbon dioxide is removed from the combustion gas 10 may be recorded at a block 158. Given by way of non-limiting example, position information of the vehicle 14 may be provided by a global positioning system (GPS) unit or the like.

Referring now to FIGS. 1A, 1Z, and 3, in some embodiments removing carbon dioxide from combustion gas from an engine of a vehicle at the block 104 may include removing carbon dioxide from combustion gas from an engine of a vehicle when a combustion gas exhaust rate is less than a predetermined exhaust rate at a block 160. In some cases, the predetermined exhaust rate may approximately represent a maximum input rate of combustion gas that can be removed at the block 104, thereby helping to mitigate inefficiencies and/or buildup of back-pressure.

In some embodiments and referring additionally to FIG. 1AA, at a block 162 the combustion gas 10 may be exhausted to atmosphere when the combustion gas exhaust rate is at least the predetermined exhaust rate. In such cases, combustion gas in excess of that which may be removed at the block 104 is instead exhausted to atmosphere, which can help mitigate inefficiencies and/or buildup of back-pressure. In some other embodiments and referring additionally to FIG. 1AB, at a block 164 the combustion gas 10 may be stored in a third vessel when the combustion gas exhaust rate is at least the predetermined exhaust rate. In such cases, the combustion gas 10 that was stored in the third vessel at the block 164 may be available for processing at the block 104 (that is, removal of carbon dioxide) when conditions permit (such as when the engine 12 is shut down or when a combination of the combustion gas 10 from the engine 12 and the combustion gas 10 stored in the third vessel is within processing capabilities at the block 104).

Referring now to FIGS. 1A, 1AC, and 3, in some embodiments data indicative of removal of carbon dioxide from the combustion gas 10 may be communicated at a block 166. Given by way of non-limiting example and referring additionally to FIG. 1AD, in some embodiments communicating data indicative of removal of carbon dioxide from the combustion gas 10 at the block 166 may include wirelessly transmitting from a vehicle the data indicative of removal of carbon dioxide from the combustion gas 10. For example, the data indicative of removal of carbon dioxide from the combustion gas 10 may be wirelessly transmitted via radiofrequency communications. In some other embodiments and referring to FIGS. 1A, 1AC, 1AE, and 3, communicating data indicative of removal of carbon dioxide from the combustion gas 10 at the block 166 may include displaying from a vehicle a visual indicator of data indicative of removal of carbon dioxide from the combustion gas 10 at a block 170. It will be appreciated that any type of visual indicator may be used as desired.

It will also be appreciated that data may be further indicative of various illustrative aspects of removal of carbon dioxide from the combustion gas 10. Given by way of examples and not of limitation, the data indicative of removal of carbon dioxide from the combustion gas 10 may be further indicative further indicative of without limitation: identification of the vehicle 12; identification of a user; amount of carbon dioxide removed from the combustion gas 10; location at which carbon dioxide is removed from the combustion gas 10; time at which carbon dioxide is removed from the combustion gas 10; and/or form in which material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 is stored.

Referring now to FIGS. 1A, 1AF, and 3, in some embodiments at least one parameter that is associated with removal of carbon dioxide from the combustion gas 10 may be modified at a block 172. Given by way of non-limiting example and referring additionally to FIG. 1AG, in some embodiments modifying at least one parameter that is associated with removal of carbon dioxide from the combustion gas 10 at the block 172 may include varying at least one setting of an engine at a block 174. For example, a setting of the engine 12 that may be varied at the block 174 may include richness of a fuel-air mixture.

In some other embodiments and referring now to FIGS. 1A, 1AF, 1AH, and 3, modifying at least one parameter that is associated with removal of carbon dioxide from the combustion gas 10 at the block 172 may include varying type of fuel at a block 176. Given by way of non-limiting examples, varying type of fuel may include without limitation: switching a hydrocarbon fuel between gasoline fuel and diesel fuel; switching fuel between a hydrocarbon fuel and electricity in a hybrid vehicle; varying octane rating of a hydrocarbon fuel; varying sulfur content of a diesel fuel; switching between a hydrocarbon fuel and electricity in a hybrid vehicle; and/or the like.

In some other embodiments and referring now to FIGS. 1A, 1AF, 1AI, and 3, modifying at least one parameter that is associated with removal of carbon dioxide from the combustion gas 10 at the block 172 may include varying a setting of a catalytic converter at a block 178. Referring additionally to FIG. 1AJ, in some embodiments varying a setting of a catalytic converter at the block 178 may include varying temperature of combustion gas from an engine of a vehicle at a block 180.

Referring now to FIGS. 2A and 3 and given by way of overview, an illustrative system 200 is provided for removing carbon dioxide from the combustion gas 10 from the engine 12 of the vehicle 10. A vessel 202 is configured to remove carbon dioxide from the combustion gas 10 from the engine 12 of the vehicle 14. A vessel 204 is configured to store material that contains carbon associated with carbon dioxide removed from the combustion gas 10. A removal mechanism 206 is configured to remove from the vehicle 14 the material that contains carbon associated with carbon dioxide removed from the combustion gas 10. Illustrative details set forth by way of example only and not of limitation will now be explained.

In some embodiments, the system 200 and its components may be configured to perform process blocks of the method 100 (FIG. 1A). For example, the vessel 202 may be configured to perform operations at the block 104 (FIG. 1A), the vessel 204 may be configured to perform operations at the block 106 (FIG. 1A), and the removal mechanism 206 may be configured to perform operations at the block 108 (FIG. 1A). Other components of the system 200 may be configured to perform other process blocks of the method 100. In such cases, process details that have already been discussed in the context of the method 100 will not be repeated.

The vehicle 14 and the engine 12 have been discussed above. For sake of brevity, their details need not be repeated for an understanding.

Still referring to FIGS. 2A and 3, in some embodiments the vessel 204 may be vessel configured to be disposed on the vehicle 14. In some embodiments the vessel 204 may be removable from the vehicle 14, and in some embodiments the vessel 204 may be removably replaceable on the vehicle 14. It will be appreciated that the vessel 204 may be any type of storage vessel as desired that is removably replaceable on the vehicle 14. Given by way of non-limiting examples, the vessel 204 may include without limitation a bottle, reservoir, tank, or the like. The vessel 204 may be sized as desired for a particular application. The vessel 204 may be made from any material as desired for a particular application.

Given by way of non-limiting example for illustration purposes only, in some embodiments the vessel 204 (that contains carbon associated with the carbon dioxide removed from the combustion gas 10) may be configured to be disposed off the vehicle 14. That is, in some cases the vessel 204 may be configured such that the vessel 204 may be removed from the vehicle 14 and brought to a collection or exchange facility that accepts containers (such as the vessel 204) that contain carbon associated with the carbon dioxide removed from the combustion gas 10. However, it will be appreciated that, in other applications, the vessel 204 need not be brought to such a collection or exchange facility.

In some embodiments (such as in some of the applications discussed above), the removal mechanism 206 may include the vessel 204. However, in some embodiments the removal mechanism 206 may include an outlet port.

Still referring to FIGS. 2A and 3, the vessel 202 may be any type of reaction vessel as desired for a particular application. The vessel 202 may be sized as desired for a particular application.

In some embodiments the vessel 204 may have a pressure that is less than the pressure of the vessel 202. In such cases, the pressure differential can help fill the vessel 204 and help mitigate back-flow from the vessel 204 to the vessel 202. As discussed above, in some embodiments (and depending upon the removal modality) a higher pressure may be entailed for removing carbon dioxide than is entailed for storing carbon dioxide.

Referring additionally to FIGS. 2B and 2C, in various embodiments the vessel 202 may contain any type of liquid solution 208 as desired, such as a liquid solvent or the like. The liquid solution 208 has been discussed above (in the context of the method 100) and its details need not be repeated for an understanding.

As shown in FIG. 2B, in some embodiments the vessel 202 may be further configured to pass the combustion gas through the liquid solution 208. In some arrangements the combustion gas may be “bubbled up” through the liquid solution 208. In some other arrangements the combustion gas may be circulated through the liquid solution 208 via forced circulation. As shown in FIG. 2C, in some other embodiments the vessel 202 may be further configured to pass the combustion gas over a surface 210 of the liquid solution 208.

In some embodiments the vessel 202 may be configured to separate the removed carbon dioxide from the liquid solution 208. For example, temperature inside the vessel 202 may be raised sufficiently to drive the carbon dioxide out of the liquid solution 208, and the carbon dioxide can be transferred to the vessel 204 for storage. In some other embodiments, the vessel 202 may be further configured to recover the liquid solution. For example, the liquid solution 208 (from which the carbon dioxide has been separated) may be cooled in the vessel 202 from its previously-elevated temperature, whereupon the liquid solution 208 may once again be used for absorbing carbon dioxide.

Referring now to FIGS. 2A, 2D, and 3, in some other embodiments the vessel 202 may be configured to adsorb the carbon dioxide with an adsorption material 212. The adsorption material 212 has been discussed above in the context of the method 100 and its details need not be repeated for an understanding.

Referring now to FIGS. 2E and 3, in some embodiments the system 200 may also include electrical circuitry 214 that is configured to determine at least one attribute regarding removal of carbon dioxide from the combustion gas 10.

As discussed above, it will be appreciated that the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may include various carbon-containing compounds, depending upon whether or not any additional processing is performed on the carbon dioxide removed from the combustion gas 10. For example, in some embodiments when no further processing is performed on the carbon dioxide removed from the combustion gas 10, the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may include carbon dioxide itself removed from the combustion gas 10.

However, in some other embodiments, the vessel 202 and/or the vessel 204 may be further configured to process the material that contains carbon associated with carbon dioxide removed from the combustion gas 10. For example, in some embodiments the vessel 202 and/or the vessel 204 may be further configured to react the material that contains carbon associated with carbon dioxide removed from the combustion gas 10 with a chemical reactant, as discussed above.

For example and referring to FIGS. 2G and 3, in some embodiments the system 200 may also include a measurement system 218 that is configured to measure an amount of stored material that contains carbon associated with carbon dioxide removed from the combustion gas 10. The measurement system 218 may include any suitable sensor as desired for sensing stored material that contains carbon associated with carbon dioxide removed from the combustion gas 10. The measurement system 218 may also include electrical circuitry as desired to determine the amount of stored material that contains carbon associated with carbon dioxide removed from the combustion gas 10.

Referring additionally to FIG. 2H, in some embodiments the system 200 may also include a display device 220 that is configured to display the amount of stored material that contains carbon associated with carbon dioxide removed from the combustion gas 10. It will be appreciated that the display device 220 may be any type of display device as desired.

In various embodiments, the measurement system 218 and the display device may be further configured to measure and display, respectively, other parameters as desired. For example, in some other embodiments the measurement system 218 may be further configured to determine an amount of storage capacity available for storing material that contains carbon associated with carbon dioxide removed from the combustion gas 10. That is, in such applications the measurement system 218 can determine the amount of storage capacity available in the vessel 204. In some cases the display device 220 may be configured to display the amount of storage capacity available for storing material that contains carbon associated with carbon dioxide removed from the combustion gas 10.

In some other embodiments the measurement system 218 may be further configured to determine a rate of storing material that contains carbon associated with carbon dioxide removed from the combustion gas 10. That is, electrical circuitry in the measurement system 218 can divide the amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 by time that elapsed during storage of the material that contains carbon associated with the carbon dioxide removed from the combustion gas 10.

In some other embodiments the measurement system 218 may be further configured to determine an amount of time remaining to fill the storage capacity available for storing material that contains carbon associated with carbon dioxide removed from the combustion gas 10. For example, the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be divided by the rate of storing material that contains carbon associated with the carbon dioxide removed from the combustion gas 10. In some embodiments the display device 220 may be configured to display the amount of time remaining to fill the storage capacity available for storing material that contains carbon associated with carbon dioxide removed from the combustion gas 10.

In some embodiments the measurement system 218 may be further configured to determine a distance travelable in the vehicle 14 with the amount of storage capacity available for storing material that contains carbon associated with carbon dioxide removed from the combustion gas 10. For example, the amount of time remaining to fill the storage capacity available for storing carbon material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 may be multiplied by speed of the vehicle 14. In some embodiments the display device 220 may be configured to display the distance travelable in the vehicle 14 with the amount of storage capacity available for storing material that contains carbon associated with carbon dioxide removed from the combustion gas 10.

Referring now to FIGS. 21 and 3, in some embodiments the system 200 may include a monitoring system 222 that is configured to record time when carbon dioxide is removed from the combustion gas 10. In such cases, the monitoring system may include any electrical circuitry suitable for creating an electronic time stamp or an electronic date-time stamp, as desired.

In some other embodiments, the monitoring system 222 may be configured to record position of the vehicle 14 where carbon dioxide is removed from the combustion gas 10. In such cases, the monitoring system 222 may include any without limitation a global positioning system (GPS) or any electrical circuitry as desired for determining position of the vehicle 14, such as LORAN, or an inertial navigation system (INS), or any electrical circuitry configured to perform dead reckoning from an initial fix of position, or the like.

Referring back to FIGS. 2A and 3, in various embodiments the vessel 202 may be further configured to remove carbon dioxide from the combustion gas 10 when a combustion gas exhaust rate is less than a predetermined exhaust rate. In some cases, the predetermined exhaust rate may approximately represent a maximum input rate of combustion gas that can be removed by the vessel 202, thereby helping to mitigate inefficiencies and/or buildup of back-pressure in the vessel 202 or the engine 12.

In some embodiments and referring now to FIGS. 2J and 3, the vessel 202 may be further configured to exhaust the combustion gas 10 to atmosphere when the combustion gas exhaust rate is at least the predetermined exhaust rate. For example, the vessel 202 may include a pressure relief device, such as a pressure relief valve, with a pressure set point above pressures associated with combustion gas exhaust rates below the predetermined exhaust rate. When the combustion gas exhaust rate exceeds the predetermined exhaust rate (and, thus, the maximum input rate of combustion gas that can be removed by the vessel 202), pressure within the vessel 202 can build up toward the pressure set point of the pressure relief device. When the pressure reaches the pressure set point, the pressure relief device can be activated, thereby porting combustion gas 10 to atmosphere.

In some other embodiments and referring now to FIGS. 2K and 3, the system 200 may further include a vessel 224 that is configured to store the combustion gas 10 when the combustion gas exhaust rate is at least the predetermined exhaust rate. For example, the combustion gas 10 may be ported to the vessel 224 (instead of to atmosphere) when a pressure relief device as described above is activated. In such a case, the combustion gas stored in the vessel 224 may be sent to the vessel 202 for removal of carbon dioxide at other times as desired, such as when the vessel 202 can accommodate input of additional combustion gas from the vessel 224.

Referring now to FIGS. 2L and 3, in some embodiments the system 200 may include a communications system 226 that is configured to communicate data indicative of removal of carbon dioxide from the combustion gas 10.

To that end, in some embodiments the communications system 226 may be further configured to wirelessly transmit from the vehicle 14 the data indicative of removal of carbon dioxide from the combustion gas 10. In some other embodiments the communications system 226 may be further configured to display from the vehicle 14 a visual indicator of data indicative of removal of carbon dioxide from the combustion gas 10.

The data indicative of removal of carbon dioxide from the combustion gas 10 may include any data as desired. Given by way of nonlimiting examples, the data indicative of removal of carbon dioxide from the combustion gas 10 may be further indicative of any one or more of the following: identification of the vehicle 14; identification of a user; amount of carbon dioxide removed from the combustion gas 10; location at which carbon dioxide is removed from the combustion gas 10; time at which carbon dioxide is removed from the combustion gas 10; and/or form in which material that contains carbon associated with the carbon dioxide removed from the combustion gas 10 is stored.

Referring back to FIGS. 2A and 3 and as discussed above, at least one parameter that is associated with removal of carbon dioxide from the combustion gas 10 may be modifiable. Given by way of nonlimiting examples, the modifiable parameter may include any one or more of the following: at least one modifiable setting of an engine, such as richness of a fuel-air mixture; type of fuel; and/or a modifiable setting of a catalytic converter, such as temperature of the combustion gas 10.

Referring now to FIG. 3, the vehicle 14 includes a vehicle frame 16. The engine 12 is disposed on the vehicle frame 16. The engine 12 and types of vehicles that may be embodied as the vehicle 14 have been discussed above and need not be repeated.

The vehicle 14 also includes the system 200 for removing carbon dioxide from the combustion 10 gas from the engine 12. As discussed above, the system 200 includes the vessel 202 that is configured to remove carbon dioxide from the combustion gas 10, the vessel 204 that is configured to store material that contains carbon associated with carbon dioxide removed from the combustion gas 10, and the removal mechanism 206 that is configured to remove from the vehicle 14 the material that contains carbon associated with carbon dioxide removed from the combustion gas 10.

The system 200 has been described above with reference to FIGS. 2A-2L. The above-description is hereby incorporated into this discussion of the vehicle 14. The discussion of the system 200 need not be repeated for an understanding and, in the interest of brevity, the discussion of the system 200 is not repeated.

It will be appreciated that the vehicle 14 is shown in FIG. 3 as an automobile for purposes of illustration only. No limitation of any sort whatsoever is intended regarding form of the vehicle 14 and is not to be inferred. To that end, the vehicle 14 may include any type of vehicle whatsoever—for travel associated with sea, air, or land—that includes the engine 12 from which it may be desired to remove carbon dioxide from the combustion gas 10.

Various additional methods related to aspects of removal of carbon dioxide from combustion gas from an engine of a vehicle are disclosed. These illustrative methods will be discussed below.

For example and referring now to FIG. 4A, a method 400 starts at a block 402. At a block 404 at least one parameter that is associated with removal of carbon dioxide from combustion gas from an engine of a vehicle is modified. The method 400 stops at a block 406.

Referring to FIG. 4B, in some embodiments modifying at least one parameter that is associated with removal of carbon dioxide from combustion gas from an engine of a vehicle at the block 404 may include varying at least one setting of an engine at a block 408. Given by way of nonlimiting example, the setting of an engine may include richness of a fuel-air mixture.

Referring to FIG. 4D, in some embodiments modifying at least one parameter that is associated with removal of carbon dioxide from combustion gas from an engine of a vehicle at the block 404 may include varying a setting of a catalytic converter at a block 412. Given by way of nonlimiting example, varying a setting of a catalytic converter at the block 412 may include varying temperature of combustion gas from an engine of a vehicle at a block 414.

As another example and referring now to FIG. 5A, a method 500 starts at a block 502. At a block 504, material that contains carbon associated with carbon dioxide removed from combustion gas from an engine of a vehicle is stored in a removably replaceable vessel. In some embodiments, the material that contains carbon associated with carbon dioxide removed from combustion gas from an engine of a vehicle may stored in the removably replaceable vessel while the removably replaceable vessel is installed in or on the vehicle. However, the removably replaceable vessel need not be installed in or on the vehicle for the material that contains carbon associated with carbon dioxide removed from combustion gas from the engine of the vehicle to be stored in the removably replaceable vessel. In some embodiments, the vehicle may be stationary and the material that contains carbon associated with carbon dioxide removed from combustion gas from the engine of the vehicle may be stored in a removably replaceable vessel that is not installed in or on the vehicle. In such embodiments, the material that contains carbon associated with carbon dioxide removed from combustion gas from the engine of the vehicle may be offloaded from the vehicle to the removably replaceable vessel via an outlet port and suitable piping. The method 500 stops at a block 506.

As discussed above, the material that contains carbon associated with the carbon dioxide removed from the combustion gas may include various carbon-containing compounds, depending upon whether or not any additional processing is performed on the carbon dioxide removed from the combustion gas. For example, in some embodiments when no further processing is performed on the carbon dioxide removed from the combustion gas, the material that contains carbon associated with the carbon dioxide removed from the combustion gas may include carbon dioxide itself removed from the combustion gas.

In some other embodiments and referring additionally to FIG. 5B, if desired at a block 508 the stored material that contains carbon associated with the carbon dioxide removed from the combustion gas may be processed. For example, in some embodiments processing the stored material that contains carbon associated with carbon dioxide removed from the combustion gas 10 at the block 508 may include reacting the stored material that contains carbon associated with carbon dioxide removed from the combustion gas 10 with a chemical reactant, as discussed above. For example and without limitation, in some embodiments and referring additionally to FIG. 5C, processing the stored material that contains carbon associated with the carbon dioxide removed from the combustion gas at the block 508 may include transforming the stored material that contains carbon associated with the carbon dioxide removed from the combustion gas into a hydrocarbon at a block 510, as discussed above.

As a further example and without limitation, in some other embodiments and referring additionally to FIG. 5D, processing the stored material that contains carbon associated with the carbon dioxide removed from the combustion gas may include transforming the stored material that contains carbon associated with the carbon dioxide removed from the combustion gas into at least one compound chosen from a carbonate and a bicarbonate. Given by way of non-limiting examples, the carbon dioxide may be reacted with sodium hydroxide to form sodium carbonate or sodium bicarbonate. As a further non-limiting example, processing the stored material that contains carbon associated with the carbon dioxide removed from the combustion gas at the block 508 may include hydrating carbon dioxide to form carbonic acid.

In various embodiments the method 500 may include any one or more additional process blocks related to the material that contains carbon associated with storage of material that contains carbon associated with carbon dioxide removed from the combustion gas. Several examples will be given below by way of illustration and not of limitation.

For example and referring to FIGS. 5A and 5E, in some embodiments an amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas may be measured at a block 514. The measurement performed at the block 514 may measure volume and/or weight, as desired for a particular application. It will be appreciated that any measurement technique and sensors may be used as desired. In some other embodiments and referring additionally to FIG. 5F, the amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas may be displayed at a block 516.

In some embodiments and referring to FIGS. 5A and 5G, an amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas may be determined at a block 518. For example, the amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was measured at the block 514) may be subtracted from the total amount of storage capacity available in an empty second vessel. In some embodiments and referring additionally to FIG. 5H, the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas may be displayed at a block 520.

In some embodiments and referring to FIGS. 5A and 5I, a rate of storing material that contains carbon associated with the carbon dioxide removed from the combustion gas may be determined at a block 522. For example, the amount of stored material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was measured at the block 514) may be divided by time that elapsed during storage of the material that contains carbon associated with the carbon dioxide removed from the combustion gas.

Referring additionally to FIG. 5J, in some embodiments an amount of time remaining to fill the storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas may be determined at a block 524. For example, the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was determined at the block 518) may be divided by the rate of storing material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was determined at the block 522). Referring additionally to FIG. 5K, in some embodiments the amount of time remaining to fill the storage capacity available for storing carbon material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was determined at the block 524) may be displayed at a block 526.

Referring additionally to FIG. 5L, in some embodiments a distance travelable in the vehicle with the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was determined at the block 518) may be determined at a block 528. For example, the amount of time remaining to fill the storage capacity available for storing carbon material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was determined at the block 524) may be multiplied by speed of the vehicle. Referring additionally to FIG. 5M, in some embodiments the distance travelable in the vehicle with the amount of storage capacity available for storing material that contains carbon associated with the carbon dioxide removed from the combustion gas (that was determined at the block 528) may be displayed at a block 530.

Referring now to FIGS. 5A and 5N, in some embodiments at a block 532 a value may be determined for the amount of stored material that contains carbon associated with carbon dioxide removed from the combustion gas. In various embodiments, the value for the stored material that contains carbon associated with carbon dioxide removed from the combustion gas may be based on quantity of the carbon removed or based on quantity of equivalent carbon dioxide removed. In some embodiments, the value for the stored material that contains carbon associated with carbon dioxide removed from the combustion gas may be determined based upon, in part, by one or more weighting factors that each depend on value of their respective attribute. The attribute for determining value of a weighting factor may be any one or more of the attributes discussed herein.

Referring now to FIGS. 5A and 5O, in some embodiments at a block 534 the stored material that contains carbon associated with carbon dioxide removed from the combustion gas may be transferred from the removably replaceable vessel.

Referring now to FIGS. 5A and 5P, in some embodiments the removably replaceable vessel may be removed from the vehicle at a block 536. Referring now to FIGS. 5A and 5Q, in some embodiments the removably replaceable vessel may be replaced in a vehicle at a block 538. It will be appreciated that the vehicle in which the removably replaceable vessel is replaced need not be the same vehicle from which the removable replaceable vessel was removed.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.

The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures may be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components, and/or wirelessly interactable, and/or wirelessly interacting components, and/or logically interacting, and/or logically interactable components.

In some instances, one or more components may be referred to herein as “configured to,” “configured by,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that such terms (e.g. “configured to”) can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise. While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”

With respect to the appended claims, those skilled in the art will appreciate that recited operations therein may generally be performed in any order. Also, although various operational flows are presented in a sequence(s), it should be understood that the various operations may be performed in other orders than those which are illustrated, or may be performed concurrently. Examples of such alternate orderings may include overlapping, interleaved, interrupted, reordered, incremental, preparatory, supplemental, simultaneous, reverse, or other variant orderings, unless context dictates otherwise. Furthermore, terms like “responsive to,” “related to,” or other past-tense adjectives are generally not intended to exclude such variants, unless context dictates otherwise.

The foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or examples. Insofar as such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof. In one embodiment, several portions of the subject matter described herein may be implemented via Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), digital signal processors (DSPs), or other integrated formats. However, those skilled in the art will recognize that some aspects of the embodiments disclosed herein, in whole or in part, can be equivalently implemented in integrated circuits, as one or more computer programs running on one or more computers (e.g., as one or more programs running on one or more computer systems), as one or more programs running on one or more processors (e.g., as one or more programs running on one or more microprocessors), as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and or firmware would be well within the skill of one of skill in the art in light of this disclosure. In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies regardless of the particular type of signal bearing medium used to actually carry out the distribution. Examples of a signal bearing medium include, but are not limited to, the following: a recordable type medium such as a floppy disk, a hard disk drive, a Compact Disc (CD), a Digital Video Disk (DVD), a digital tape, a computer memory, etc.; and a transmission type medium such as a digital and/or an analog communication medium (e.g., a fiber optic cable, a waveguide, a wired communications link, a wireless communication link (e.g., transmitter, receiver, transmission logic, reception logic, etc.), etc.).

Those skilled in the art will appreciate that the foregoing specific exemplary processes and/or devices and/or technologies are representative of more general processes and/or devices and/or technologies taught elsewhere herein, such as in the claims filed herewith and/or elsewhere in the present application.

One skilled in the art will recognize that the herein described components (e.g., operations), devices, objects, and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are contemplated. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar is intended to be representative of its class, and the non-inclusion of specific components (e.g., operations), devices, and objects should not be taken limiting.
